A SiO<sub><i>x</i></sub>‐Based Anode in a High‐Voltage Lithium‐Ion Battery
Bibliographic record
Abstract
Abstract A novel synthetic procedure for the preparation of a SiOx‐based nanocomposite, involving gelification of resorcinol‐formaldehyde and tetraethyl orthosilicate, is reported. The composite is characterized as an anode material in a lithium‐ion battery. The micrometric, amorphous material has a characteristic nanostructured configuration and shows an electrochemical process involving both the alloying of Li−Si and the insertion of Li into the hard carbon matrix. The electrode reveals in a lithium half‐cell a relatively low impedance and a reversible capacity ranging from 650 mAh g−1, at the lower current, to 400 mAh g−1 at high current regimes, with a cycle life extending to 200 cycles. The anode is combined with a high‐voltage LiNi0.5Mn1.5O4 spinel cathode in a 4.3 V lithium‐ion battery delivering a capacity of about 115 mAh g−1 and operating at the high rate of 5C. The suitable synthesis pathway, the low cost and the promising electrochemical behavior suggest the nanocomposite anode for application in high‐performance lithium‐ion battery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
